How to check if queryset is empty, without querying the database?
In Django, is there any way we can check if a queryset is empty or not, without querying the database. I know that .exists() is the least expensive one, but it still hits the database. So how do I check for queryset existence, without hitting the database? -

Annotate queryset with boolean where one field is equal or not to another field
Question is regarding annotation in Django. For example I have a following model: class Example(models.Model): field_1 = PositiveIntegerField() field_2 = PositiveIntegerField() And I want to annotate queryset based on this model with boolean True or False based on whether field_1 == field_2 I managed to find 2 solutions on this, both of that don't satisfy me. Example.objects.extra(select={'equal': r' field_1 = field_1'}) Use Raw SQL, and extra() that is about to get deprecated. 2) Example.objects.all()\ .annotate( equal= Case( When(field_1=F('field_2'), then=True), default=False, output_field=BooleanField(), ) ) Which is quite verbose and makes queryset 4 times slower. Question is - is it possible to express such logic in Django ORM without useage of RAW SQL and with less verbose and more straightforward logic? Thank you. -
Django foreign key relationship in model.py problem
I am new to django and don´t know how to solve the problem(google and stack didnt "helped"/i dont get it). Since yesterday i tryed many options. This is my desired output: enter image description here Function.py def test(): .... return(author, title, view....) Models.py class Pers(models.Model): author = models.CharField(max_length=50) class Title(models.Model): authors = models.ForeignKey('Pers', on.delete=models.CASCADE) title = models.CharField(max_length=20) view = models.CharField(max_length=10) p = test() t = Pers(author = p[0]) t.save() z = test() y = Title(authors = z[0], title = z[1], view = z[2] y.save() My Function.py works fine but i have problems with the db. I can fill the Pers-Table with "DJ ES" but i want to have it just one time( ID[0] = DJ ES, ID1 = MAX VA and so on). With my table i get multiply DJ ES(ID[0] = DJ ES, ID1 = DJ ES, ID[2] = DJ ES....). And i am not able to save DJ ES to my Title-Table. My latest error: ValueError: Cannot assign "'DJ ES'": "Title.authors" must be a "Pers" instance. " -
How to set initial value of ForeignKey dynamically in CreateView?

Django send email after deleting object
I hope someone will be able to help. I am new in Django and struggling with sending email after using CBV DeleteView.

Django perform division in annotate sum expression and return as float

I would like to sum 1 / rank and group it by date and filter by some value from the foreign_key. The raw sql would be something like SELECT SUM(1/rank) FROM ... WHHERE [foreign key constraint] GROUP BY date I've tried the following in Django: data = MyModel.objects.values('date').annotate( score=Sum(1/F('rank'), filter=Q(myforeignobject__bla__bla__name="Some name")) ) The worked somewhat, but the resulting score is an integer which won't work since the numbers will usually be very small. I also tried the following, but still get and integer: data = MyModel.objects.values('date').annotate( score=Cast(Sum(1/F('rank')), FloatField()) ) Note, I do not want to sum rank and then have it be divided by one, it has the be one divided by each entry since it won't yield the same result otherwise. -

Django-REST or Firebase?
We are about to begin working on a project that was started by someone else. It is currently developed in HTML+CSS+Javascript and Firebase. We'll move the frontend to React, but we are used to develop the backend on Django-REST deployed on AWS and have never really worked with Firebase (and honestly, don't really know how it works in detail). React seems to have a nice integration with Firebase, but we would need to learn how it works. Is it worth it to move the backend from Firebase to Django-REST? Which are the pros and cons of both of them? Thank you in advance! -

using NamespaceVersioning in drf-yasg - Yet another Swagger generator
I'm facing the same issue with swagger (drf-yasg) and django as this thread: https://github.com/axnsan12/drf-yasg/issues/128 When I give a default version in my REST_FRAMEWORK settings it only gives the endpoints of v1. When I don't give any default_version, it gives all the endpoints of all the versions. I would like to have only the endpoints of v1 when the url is like .../v1/... (and get the version out of the url, but that is not the big issue) However, after hours of trying this code/solution, it didn't do the trick.

How to evaluate a queryset in batches?
I have a model with 100,000+ rows. I want to do some operation on it, but can't do it in one go, because of the size. So, I thought of using Paginator like this: def fun(): paginator = Paginator(Model.objects.filter(**some_filter), 10000) for page_no in paginator.page_range: page = paginator.get_page(page_no) queryset = page.object_list # Do some operation on queryset # Check if new records are added in the Model, (if yes, then do the operation on new records only) The final comment in the code says, that while running the above code, if new records are added (because this is a live application), then we have to do the same operation on those records too. So my question is how do I get the remaining (new) records only to run the same code? -
Can I use a for loop counter where there is a number in the property names in Django?
I have this html code but I have 20 products and the only code that changes in them are the image1 caption1 product1 etc. I'm new to Django and not sure if this can be done with a for loop using a counter or if it can be done with an {% include ___ with ____ %}? Or can it be done with Python code? I'm even newer to Python and wouldn't be sure how to do that. I tried a for loop counter but it said i couldnt do {% image page.image{{ forloop.counter }} fill... %} as it expects the %} before the {{ }} {# Product1 #} <div class="document product-card"> <div class="w3-card-4 w3-margin w3-white" data-aos="fade-down"> {% image page.image1 fill-150x150-c100 %} <div class="w3-container"> </div> <hr> <p id="caption">{{ page.caption1 }}</p> {% for download in page.product1.all %} {% with doc=download.product1 %} <div class="download product-info"> <a href="{{ doc.url }}" class="smooth-over-button noDecoration"> <i class="fa fa-download"></i> <p class="btn-txt">{{ doc.title }}</p> </a> </div> {% endwith %} {% endfor %} </div> </div> -
Distinguishing Between Multiple Submit Buttons On The Same Page
I am printing multiple file upload buttons to a page, one per iteration through my loop. {% for unit in user.units.all %} {% if unit.number|add:0 == iteration|add:1 %} <button type="button" class="btn btn-primary js-upload-photos"> <span class="glyphicon glyphicon-cloud-upload"></span> Upload Files</button> <input id="fileupload" type="file" name="user_file" multiple data-url="{% url 'user-file-upload' %}" data-form-data='{"csrfmiddlewaretoken": "{{ csrf_token }}", "unit_id":"{{ unit.id }}"}'> $(function () { $(".js-upload-photos").click(function () { $("#fileupload").click(); }); $("#fileupload").fileupload({ dataType: 'json', done: function (e, data) { if (data.result.is_valid) { $("#gallery tbody").prepend("<tr><td><a href='" + data.result.url + "'>" + data.result.name + "</a></td></tr>") } } }); }); As each fileUpload matches a different unit, I am passing a unit_id variable to javascript with the button press. This variable is to be saved in the DB along with the file. If I inspect the page, each fileUpload has a unique unit_id but it doesn't matter which of the fileUploads' UPLOAD FILES button I click on, the id saved in the DB is always for the first unit. I suspect this is because each fileUploads has the same id, but I am unsure how to change this without breaking my code. I thought maybe I could change the id in my template to class and the two #fileuploads in my javascript … -
